I believe in play everywhere. We are slowly transforming our yard into a playable garden.
This year we added wild flowers to the flower bed in front of the house. The number of butterflies and bees constantly getting their fill of nectar is astounding. There were a few comments about the "jungle" in our yard, but that pales to the admiration of the grandchildren when they spot a monarch butterfly.
Next spring, I'll do a green teepee in the midst of the vegetables. Won't it be great for children who drive or walk by to giggle and say, "Let's do THAT in our yard!"?
